This EF 40mm f/2.8 STM Lens from Canon is a welcome addition to Canon's line-up of EF lenses--a light, inconspicuous "normal" lens. At a featherweight 4.6 oz, this is one of the lightest lenses in the EF family. It's less than one inch long, so it will never draw unwelcome attention to you when you're shooting in public. A bright f/2.8 maximum aperture allows you to shoot under pretty much any lighting conditions, and the sophisticated lens configuration, including one aspherical element, guarantees high image quality from the center to the edge of the frame. The optimized coatings used in constructing the lens greatly reduce ghosting and flare, and deliver superb color balance.

STM functionality provides quiet, smooth and continuous autofocus during video operation (continuous video autofocus only when used with the Canon EOS 70D, Rebel T4i and T5i). The circular aperture formed by 7 diaphragm blades combined with the wide aperture can give you beautiful bokeh--the out-of-focus background areas of your images. This 40mm lens will give you a view equivalent to 64mm when used on a camera with an APS-C sensor, and is able to focus as close as 11.81".

Newly developed STM technology for smooth and quiet continuous AF while shooting video (continuous video autofocus only supported with EOS 70D, Rebel T4i and T5i cameras).
Lightweight and unobtrusive 4.6 oz lens is less than one inch long.
Bright f/2.8 aperture is effective in low light situations and provides shallow depth of field focus control.
High image quality from the center to the periphery thanks to its advanced lens configuration including one aspherical element.
Optimized coatings that minimize ghosting and flare while providing exceptional color balance
A circular 7-blade aperture for beautiful soft-focus backgrounds
Short minimum focusing distance of only 11.81"
Mounted on a camera with an APS-C sensor, this lens offers a view similar to a 64mm lens in the 35mm format.

    Great lens. Quite sharp. Accurate and fast focus. It's a joy to use. Of course, it delivers in terms of being compact. I'm using it on a 1.6x camera, so it's a somewhat awkward focal length. I look forward to the day I get to use it on a full frame. But you all know it's 40mm, so onward.

    The mounting ring is really tight with my camera, and I have this feeling that I'm grinding something down when I mount or remove the lens. I don't think it hurts anything, so that's fine with me.

    Unfortunately, the lens data is not pre-loaded on my t4i. But the image quality is so good that you hardly would ever need it. I will include a couple of photos. Both are unedited and were taken with in-camera settings neutral, and sharpness set to 0. The one of the leaf was taken with the lens wide open. You can see how quickly it passes in and out of focus. The background light shows the chromatic aberration about as badly as it ever gets, which is hardly at all! You can just barely see the opposing red vs. green fringe in the light. The one of the flowers is also wide open at 2.8, also neutral and unsharpened and unedited. With even the most light-handed increase of sharpness and contrast, stunningly crisp images, as well as softer ones, are at your disposal, and all at a ridiculously low price. I really like it, and it manages to jostle my other lenses off the camera which, on paper, should have much more versatility and utility.

    Another note: The STM focusing is not silent. This is fine with me, but for those of you who might be interested, read on. In AF, there's a soft whine that it gives off, louder than my USM lens but quieter than my kit lens. In manual mode, the focus ring is, as many have pointed out, NOT a mechanically engaged gear, but rather an electronic input. When turning the ring medium to fast, it makes a lower and slightly softer hum. When turning the ring slowly, it makes a rather disturbing groan. However, when you turn it REALLY slowly, the focus moves with an amazingly controlled slow creep, and it's _completely silent_. That could come in handy for some nice cinematic effects.

    I got this lens so I could take some more closeup candid photos of family on my 10D. It's been great. The low profile of it makes it more convenient in tight spaces and for carrying around. With its short macro distance I've also been taking some nice pictures of flowers.

    The autofocus is a bit slow in my mind, but it's accurate. The lack of a distance meter is not too big of a problem. Its size made me a little wary about screwing it into my camera without breaking it, but it's a solid fit.

      Comments about Canon EF 40mm f/2.8 STM Lens:

      When thinking about cameras to take on an upcoming vacation, I was seriously considering buying a Micro 4/3rds Mirrorless camera because I was tired of lugging around my 7D with my 24-70 USM L lens. Faced with the prospect of spending $-$ for a decent camera, I found this sweet little lens that essentially halved the wight and bulk of my 7D setup. Now I'm much more comfortable throwing this kit into my backpack and hiking all day. The croopped 60mm focal length fit perfectly into the sweet spot of the 24-70. (Would love to see something wide in a pancake lens from Canon though at some point). The fast focusing STM motor and sharp imagery of this lens makes it a joy to use. f 2.8 is fast enough for most subject matter and light conditions. The shallow DOF allows for nice creamy bokeh but is also flexible enough to take decent landscapes. I would highly recommend this lens (especially for the $$)

        When you mount the lens it's so small it doesn't look like you have a lens on. I used it for some street photography, it's sharper stopped down, a fun lens to have in the bag.

        from Albuquerque

        Comments about Canon EF 40mm f/2.8 STM Lens:

        Super compact lens. Sharp, quick enough focusing. Certainly not the fastest focusing lens I own, but more than good enough. Great on a full size DSLR, and great on the EOS-M with the adaptor. Nice to have a fast small lens for many common shooting situations.

        Great little lens! Very light to carry (perfect for exploring a city without weighing yourself down) and super sharp. It's not perfect for a crop (probably 35mm would be better) and at 2.8 it's slower than I wish it was. But for $ it's a great buy and a great addition to a lens set. No regrets at all. Sturdy build quality too!

        Comments about Canon EF 40mm f/2.8 STM Lens:

        I'm pretty shocked on how good this lens is. I decided on this lens as my first Prime over either of the Canon 50mm's based on the focal length with my crop sensor body. This lens is pretty fast, and very very sharp. I have been very pleased with it and works well in lower light situations. I don't think you can go wrong with this lens.

        Although its not a 1.8 or 1.4 it still has a nice DOF/Bokah, but in order to achieve it, you will have to get the lens pretty close to the in focus subject. This lens is light weight, its easy to walk around with, it focuses very fast on my 70D, and the image quality is well worth the money.

                This little darling has made my SLR suddenly quite portable. It doesn't zoom but my computer does that quite well. I like the photos I've taken so far, but have yet to see a major difference between it and my old kit lens. I gave it one less star because of this, but that may not be fair because I haven't sufficiently tested it yet.

Paired with my new (B&H used) Canon 100D, it's my favorite lightweight setup to date, and I use it everyday. The depth of field is great, it's inconspicuous, and it's fast. Wonderful lens!

                              I cannot believe how inexpensive this lens was in comparison to the great results it gives.

                              I love just how flat this lens is. It feels so light and easy to carry around. It's pretty fast although sometimes the focus is off. For the price I get it's very affordable.

                              Not Just A Novelty Lens

                              Comments about Canon EF 40mm f/2.8 STM Lens:

                              I bought this lens to achieve a light weight set up for my brushless gimbal. I was blown away by the image quality! I own a few L series lenses and this lens fits in well. It literally feels as if there is no lens on your camera body.

                              Pros:
                              Light weight
                              Great image quality
                              Fast aperture
                              Inexpensive

                              Cons:
                              Medium speed autofocus locking (not slow or fast)

                                With all the hype over the nifty-fifty, this little gem tends to be overlooked. Although not quite as fast as the 50/1.8, it does have two advantages: it is more compact, and it has a potentially more useful focal length for crop sensors (depending on what you are shooting). And for some, the STM motor might also make a difference (it doesn't for me so I can't speak to it). Granted 10mm doesn't seem like much and probably most already own the 50mm/1.8, so it may not be for everyone. Do not underestimate the 10mm difference on a crop sensor however - it does make a difference for some applications like street photography.

                                  This small, fast lens is an amazing little guy. If my 70-200 isnt on my Canon, THIS lens is. its not intimidating like the 70-200 is, which is great especially when taking pictures of people who aren't so fond of photos of themself. I havnet had issues of it autofocusing, and its super quiet. Its so small, I actually recommend NOT getting the UV filter, it adds 25% more length to the lens! haa. The only thing Im not a huge fan of is the focus ring. Its electronic meaning I cant use a Macro attachment, and expect it to focus.

                                  It takes up hardly any space in my lens. and its not hard to do a portrait shoot with JUST this little lens.
